BRICK- MOLD.

SPECIPICATIQN forming part of Letters Patent No. 385,552, dated July 8,18 88.

Application filed December 31, 1887. Serial No. 259,517. (No model.)

T 06% whom it may concern:

Be it known that 1, JAMES GRANT, a citizen of the United States,residing at Goshen, in the county of Elkhart and State of Indiana, haveinvented certain new and useful Improvements in Brick-Molds; and I dohereby declare that the following is a full clear, and exact descriptionof the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of referencemarked thereon.

This invention relates to certain new'and useful improvements in devicesfor molding or making bricks, and has for its object to simplify andcheapen the construction and to render more efficient in operation thisclass of devices.

The invention consists in the peculiar combinations and the novelconstruction, arrangement, and adaptation of parts, all as more fullyhereinafter described, shown in the drawings, and then specificallydefined by the claims.

In the accompanying drawings, which form a part of this specification,Figure 1 is a bottom plan of a single mold constructed in accordancewith my invention. Fig. 2 is a vertical section of the same through theline as a: of Fig. 1, looking in the direction of the arrow in saidfigure. Fig. 3 is a bottom plan, on a smaller scale, of a twin mold.

Referring now to the details of the drawings, A designates a plate whichforms the top of the mold. To the top of this plate are rigidly securedthe transverse bars B, the outer ends of which are connected by the rodsa, on which are fulcrnmed the levers G, the upper ends of which arejoined by the rods b,which serve as operating-handles. To the lower endsof the levers are rigidly attached the plates D,which form the sides ofthe mold. The ends of the mold are formed by the plates E,piv otallyconnected at one end to one of the side plates,D, and their other endsbent inward or toward each other and extended beyond the other sideplate, D, said bent part being provided with a longitudinal slot, 0,with which engage the wedges d on the side plate, as shown.

The edges of the mold are all sharpened, as shown, so as to do cleanwork and leave the corners of the brick perfect. The same prin ciple maybe applied in double molds, or for making three or more bricks at atime. In Fig. 3 I have shown a twin mold constructed substantially likethat just described, except that I use but one cross-bar, B, for eachmold instead of two, as in the construction shown in Fig. 1.

To hold thelevers at their maximum distance apart, as shown in fulllines in Fig. 2, I provide the following means: Connecting the leversattached to one of the side plates of the mold is the angular bar 0. Fis a rod, swiveled at one end in a block, G, pivoted between the leversattached to the opposite side plate, and provided at its other end witha notch, f, to engage said angular bar, as shown in Fig. 2. This 'rod Fis preferably provided with a ring, F, by which it can be manipulated.

The operation is simple and is as follows:

The rod F is disengaged from the angular bar 6, and the free ends of thelevers brought toward each other, when the parts assume the positionsindicated in Figs. l and 2 in dotted lines. The mold is then forced intothe clay or other plastic mass from which the brick is to be formed, andthe free ends of the levers forced from each other, as shown in fulllines in Fig. 2, which brings the parts into the position indicated byfull lines in said Fig. 2, the notch of the rod F automatically engagingthe angular bar 6 and holding the parts in its position. To get a smoothsurface on the lower side of the brick, it is rubbed on a plank or othersuitable surface while in the mold. The rod F is then turned on itspivot to disengage the bar 6, and the mold opened and the brickreleased.

WVhat I claim as new isl. The combination, with the mold having movableside plates and the levers for mov ing said plates, of the end platesattached at one end to one of said side plates and at the other slotted,as described, to engage projections on the other side plate, as setforth.

2. The combination, with the stationary top plate, the transverse barssecured to the top thereof, and the levers fulcrumed on said bars, ofthe side plates carried by said levers,

hereunto subscribed my name in the presence of two witnesses.

the end plates secured at one end to one of said side plates and attheir other ends bent inward and slotted, as described, and

the Wedges carried by the last-named side 5 plate and engaging the slotsof the end plates, lVitnesses:

as shown and set forth. A. KAATZ,

In testimony that I claim the above I have 1 A. MEYER.
